This is no answer to the problem but give a few resources that show there might be issues with a 4L60E trans. I always like to look at the "technical service bulletin" titles on www.alldata.com http://www.alldata.com/TSB/11/951133fv.html the titles can sometime give a clue others have the same problems. Another thing to try is google the 4L60E trans/transmission or tranny and see what others might have posted on other forums like this site http://www.hotrodders.com/forum/4l60...ion-72358.html After looking these sites over I would say it possible to have a slippage problem at only 92,200 miles. If you dont know anything about fixing trannys I would take it in to a shop for a diagnostic test before it gets worst and burns out the clutch's.

My brother had the a slippage problem on his Dodge Dakota he took it to a Dodge dealer. All they had to do was remove the oil pan to replace this solinoid. He found this was a common problem on a Dakota so he took the TSB number he found on Alldata in to the service shop and we dont think they bothered trying to use this information to help find the problem sooner because I think they wanted to milk the labor cost on to the job. A $50.00 part cost him $800 in labor to replace without having to remove the tranny itself, so beware.

 

could be any number of things, but heres a suggestion. if your speedo needle is acting up as well, then its the vehicle speed sensor
